The Schedule reen'ed to ile these Letters Patent and making part of theIams.

Be it known that I, ROBERT A. HUNTER, of Ionia, in the county of Ionia,State of Michigan, have invented a new and useful improvement in caloricgenerators, conductors, and distributers; and I do hereby declare thatthe following is a full, clear, and exact description thereof, whichwill enable others skilled in the art to make and use the same,reference being had to the accompanying drawings, forming a part of thisspecification, and to the letters of reference marked thereon.

Like letters indicate like parts.

Figure 1 shows a part of my ihvention in perspec- Figure 2 shows the boxor vessel, in which hot air is generated, as having a double chamber.

Figure 3, the same, with single chamber.

This invention has for its object to furnish a simple, cheap, andeffective means of generating hot air, and other than that in which theheater sits, as desired. A, in the drawings, represents an ordinaryboxstove.

B is the box in which the hot air is generated, which I term thegenerator.

It is a cast-irou box, having a flange, O, all around the outside,midway between its top and bottom, and corresponds in size and shape tothe top of the stove, in which it is dropped as far as the flange.

D is the smoke-hole, in the rear end of the generator.

E Eare orifices, in which the cold air enters.

A thin iron plate, F, is fitted tightly in the inside of the generator,in a plane with the flange on the outside; thus it is divided into twochambers.

On the top side of the plate F, strips of Sheet-iron, G G, are set upedgewise, equldistant apart, and are tightly fitted to the plate.

`The stove-top Y fits all the edges of the strips' and sides of thegenerator, but air-passages are left at the ends of one strip, and inthe middle of another, alternately.

Air entering cated by the darts, H, through which under chamber.

Strips of Sheet-iron, M M, are therein arranged, so that the air canonly pass around the lend of one, and the opposite, end of the other,alternately, until it reaches the mouth of the conductor, O, bythecourse iudicated by the darts in the drawings.

The conductor is arranged within the stove Z, coming out at the elbowZ', and entering the distrihuter, P, which is arranged in the floorand'ceiling like a` common ventilator, through which stove-pipes passinto an upper room before entering a flue, as is sometimes P, isfunnel-shaped somethe orifioes E E takes the course indiuntil it reachesthose in front, H it is drawn by the draught in the what. j

outside and lining to air freely between, to burn the Woodtributer, itsforce is not broken in its ascent.

The couductor, O, is provided with a valve, V, to

shut ofl' so much of the hot air as is desired to be conducted elsewherethrough side pipes. o The side pipe S connects with the conductor, O,and is inserted within a larger pipe, X, which connects with thedistributer, P. Air is allowed to circulate within the larger pipe, andenters through perforations in the side of the distributer.

Side pipes, to conduct the hot air to other apart ments, are arrangedbeneath the floor, between it and the ceiling Z w The distribnter isused on the end of all branchpipes, having its top secured in the floor,though the bottom need not reach through the oeiliug.

Side pipes enter the sides of branch distributers, the connection andmeans for ventilation being the same in those as in the distributer, P,hereinhefore described.

Fig. 3, in the drawings, shows the generator arranged with singlechamber. The air enters the orifices E E, and passes iu the directiouindicated by the darts, until it reaches the orifice a', through whichit passes, 'in the course indicated by the darts,l until it reaches themouth of the conductor, O, thence taking 'the course hereinbefore shown.

The damper W, in the pipe S, is to shut the hot air oh", if desired tobe done, in order to keep it all in one room.

The means for ventilating the distributer, P, and side pipes, byarranging them in larger casings, and admitting cool air throughperforations, as shown, is not new in itself, as I am aware that thismode of ventilation has been used in connection with other devices, andI do not claim to have oonceived the idea of placing tubes to conducthot air from one apartment to another, between the ceiling and floor,nor do I claim to have conoeived the idea of arranging a hot-airlconductor within a stove-pipe, and passing it out in the elbow; .butz

What I do claim as new, after having thus vfully described my invention,and desire to secure by LettersPatent, is-

1. The generator B, arranged with a double or single chamber, as shown,and being arranged to set in the top of the stove O, and having flangeU, orifices E E, and smoke-hole D, 'substantially as and for the purposeset forth.

2. Oonstructing the distributer, O, funnel-shaped, l as shown, andproviding it'with a conical-shaped lid,

presented by the lid, and, as it passes from the dis-- A, and to connectwith the conduetor,

', substantially as shovn, and for the pnrpose set orth.

3. Connecting the pipe S, within the distributer, P, to the condnctor,O, and providing it with a darnpel', W, as and for the purpose hereinspecified.

4. As a combination, the means described for ventilating thedistributers and side pipes, and arranging the latter between theceiling and floor, to 'connect the main conduetor with otherdistributers, and the arrangement of lthe conduetor, O, within thestovepipe Z, and passing it out at the 'elbow Z', when it is used toconnect the generator B with the distributer, P, substantiall'y as andfor the pnrpoe herein specified.
